    摘要: A process for performing, a coupling reaction between acetaldehyde and a terminal alkyne to yield a hydroxyalkyne is described comprising the steps of; (i) reacting without solvent, a terminal alkyne with a Lewis acidic metal salt in the presence of a alkanolamine ligand and a cyclic amine base to form a metal-alkyne complex, and (ii) adding a solution of acetaldehyde to the metal-alkyne complex.

    摘要: The present invention provides a process for producing an acetylenediol continuously by reacting a ketone with acetylene in the presence of an alkali catalyst, which process comprises continuously feeding, into a first-stage reactor, a reaction solvent, an alkali catalyst, a ketone and acetylene to give rise to a reaction, continuously introducing the reaction mixture into a second-stage reactor, and continuously feeding a fresh portion of the same ketone into the second-stage reactor to give rise to a reaction.
